Description
Conversion/upgrade kits include everything you need.
Normal wear and tear of aging electro-mechanical trip devices on low-voltage circuit breakers can lead to loss of calibration that jeopardizes system coordination, protection and reliability.
ABB has channeled its decades of trip system experience into the development of the EntelliGuard TU Trip Unit, which incorporates advanced algorithms that enable arc flash protection and selectivity at the same time.
Upgrade and conversion kits are ANSI C37.59 design verification tested to ensure safe, reliable operation.
These kits extend the life of your mechanically sound breaker and they:
- eliminate costly downtime due to nuisance tripping via a Waveform Recognition Instantaneous Algorithm
- improve electrical power system coordination and protection
- permit easy upgrades to communicating Power Management Control Systems (PMCS), open Modbus RTU protocol
- enable the implementation of RELT and Zone Selective Interlock Instantaneous to reduce arc flash energy levels
EntelliGuard TU new features compared to MVT.
